Specifications JK-04PL-III is polycarboxylate ether based high performance copolymer designed for highest concrete quality. Introduction: JK-04PL-III is polycarboxylate ether based high performance copolymer designed for highest concrete quality. It enables concrete to be produced highly workable at low dosage with improved slump retention. Compared to traditional superplasticizers, JK-04PL-III has higher water reduction, little bit lower slump retention, and higher early strength than others. Feature: Makes the quality control of concrete easyHigher slump retention applications for high strength concrete Not sensitive at temperature and materials variationsIncreases segregation resistance, less bleedingProvides excellent workability without an increase in water contentIncreases pumpability and workability with low concrete viscosityImproves durabilityImproves the mechanical properties of concrete such as compressive, flexural, and tensile strength. Reduces shrinkage and cracks, coming from the increase of water content in concreteKeeps the water/binders to a minimum Application: High volume fly ash or blast furnace slag or silica fume concrete High performance concrete, High strength concrete, Pre-casting concrete, Pumping concrete, Shotcrete, Light-weight concrete, etc. Especially Water reducer with slump retention requirement of concrete. Concrete with aesthetically superb surface Dosage: The usual dosage of this product is 0.2-0.5% of the weight of cementing material.( dilute to 20% solid content) . Package & Storage: 200 kg IBC drums. The ideal storage temperature is 5-40C, avoid sun, rain, and freezing. Once freeze, it can be used after melting and mixing. The self-life is 6 months in original tightly closed drums.

Jk-04pp high range water reducing concrete admixturepolycarboxylate superplasticizer (powder)astm c494, type f descriptionjk-04 pp is a high performance based on polycarboxylate, specifically developed as effective dispersant, fluidized and high range water reducing concrete agent. jk-04 pp is a neutral concentrate grade, it is mainly used as a raw material to produce different types of high performance water reducers for targeted industrial. It complies with astm c 494, type f specifications. uses1. jk-04 pp can be applied in a wide variety industry and can improve the workability to the concrete and to improve high early compressive strength, even with low water/cement ratios while maintaining normal levels of workability. 2. it can be widely used in conventional concrete, pumping concrete, super-fluid self-compacting and high-performance concrete; it has the excellent performance especially in the application of high-strength high performance concrete. advantage1. high water reducing rate and excellent plasticizing effect. And produces concrete with high levels of workability without segregation. 2. excellent dispersion and self-compacting effect can produce different grade strength super fluid self-compacting concrete. 3. can be a substantial increase in early and late strengths of concrete, so that increase the project construction schedule. 4. better plasticity-maintaining could significantly prolong the transit time of concrete, it reduce economic losses and ensure the normal pumping of concrete. 5. improves the frost resistance and carbonation resistance of the concrete. Lower drying shrinkage of the concrete by 20% or more compared with naphthalene-based admixtures. 6. high applicability: it can be used with different variety of cement. 7. improved finished concrete surface ability. 8. proffer air environment protect. 9. no chloride ions and no corrosion to steel bar. dosage 0.18 to 0.22% by weight of cement. Standard water reduction at normal dosage and significant water reduction at higher dosage. Exact dosage rates are dependent on the type of effect sought, quality of cement and aggregates, water/cement ratio and ambient temperature. Therefore, in many cases it is advisable to carry out trial mixes. specification items specificationappearance light yellow powdersolid content (%) 98.01.0density (23??)(kg/m3) 51010chloride content (%) ?0.10na2so4 content (%) ?4.0na2o+0.658k2o (%) ?5.0solubility excellent cement paste flow ?240 technical data sheetitems specificationwater reducing rate % ?25 compressive strength ratio % 1 day ?1703 days ?1607 days ?15028 days ?130air content % ?6.0bleeding ratio % ?60shrinkage (28 day) % ?100setting time difference min. initial -90+120finally chloride penetration, coulomb ?2000f/t cycles, time ?300slump retention (60min) mm ?150 cautions 1. cannot be added together with rosin soup air entrainer. 2. cannot be kept in metal container for too long. 3. when mixing and measuring the slump loss, be aware that it takes longer time to be in effect than naphthalene admixtures. 4. do not mix with naphthalene-based admixtures. If other admixtures, such as set retarder or corrosion-inhibiting admixture, are required simultaneously for some special projects, compatibility tests should be conducted beforehand. package, storage & shelf lifefor powder: woven plastic bag with film liner. Net weight: 25kg +/- 0.2 kg. It should be stored in a dedicated warehouse that is well-ventilated and dry and keep away from moisture and direct sunlight. Shelf life: minimum 12 months. After the expiration date, it can be used if testing results is qualified.
